As electricity demand rises sharply across the United States, so does the need for robust grid infrastructure. One place where this shift is clearly visible is GE Vernova’s Grid Solutions facility in Charleroi, Pennsylvania—a 332,000-square-foot manufacturing site that has been producing high-voltage instrument transformers and circuit breakers for over 30 years.

These are not standard household breakers. The units built in Charleroi are massive, capable of handling up to 500,000 volts and 5,000 amperes, and often require flatbed trucks for transport. Each product is engineered to meet specific customer requirements, whether for utilities or large-scale data centers. This high level of customization, combined with manual assembly and rigorous testing, presents a major operational challenge—especially as demand continues to accelerate.

According to plant manager Altay Keresteci, demand has surged dramatically over the past 18 months. The facility has already undergone rapid expansion, with its workforce doubling over the last five years. The growing need for grid infrastructure—driven by artificial intelligence, data centers, and renewable energy—has placed additional pressure on production capacity.

To address this, GE Vernova announced in January a $600 million investment in U.S. manufacturing, including upgrades expected to create around 260 new jobs at facilities in Charleroi and Clearwater, Florida. However, expanding physical capacity takes time and significant capital. As a result, the Charleroi team turned to lean management principles, focusing on continuous improvement to increase efficiency without major infrastructure expansion.

This effort culminated in a “kaizen week” in February—a series of intensive workshops aimed at identifying and implementing process improvements. The primary objective was ambitious: significantly increase production of the plant’s largest circuit breaker, the DT2-550, with a goal of boosting output fivefold by year-end.

“Lean is the most effective tool we have,” Keresteci explained. “We can’t expand the facility overnight, but we can optimize what we already have.”

By the end of the week, the team reduced assembly time for the DT2-550 by nearly two-thirds. Equally important, the process established a foundation for ongoing improvements.

Operational Efficiency Through Lean Thinking

The kaizen initiative at Charleroi reflects a broader adoption of lean methodologies across GE Vernova. Senior leadership, including CEO Scott Strazik, participated directly in the workshops, helping teams reframe challenges and identify new opportunities.

Strazik noted that production volumes for some products have increased by as much as 700%, achieved largely without major capital investment. Instead, the gains are driven by improved processes and operational discipline.

This transformation comes at a time when U.S. electricity demand is undergoing a fundamental shift. After decades of modest growth, consumption is now projected to rise by 16% over the next five years. Key drivers include the expansion of AI-powered data centers, increased domestic semiconductor production, and the growing adoption of electric vehicles.

Optimizing Production of Critical Equipment

At the center of the initiative is the DT2-550 circuit breaker—a high-capacity unit designed to operate under extreme conditions, including earthquakes, high temperatures, and corrosive environments. As a critical safety component, each unit undergoes extensive testing before leaving the factory, creating potential bottlenecks in production.

During the kaizen process, teams conducted detailed workflow analysis, including a “spaghetti diagram” that mapped employee movement. The findings revealed that workers were walking more than a kilometer per shift—an inefficiency that could be significantly reduced.

Additional challenges included shared equipment constraints, such as wait times for overhead cranes, and time-consuming assembly steps. In response, the team introduced practical solutions, including new fixtures that reduced reliance on cranes and process adjustments that eliminated unnecessary rework.

Incremental Improvements, Measurable Impact

Further gains were achieved by improving material flow and organization. For example, components delivered out of sequence were reorganized to reduce handling time, while better sorting of tools and materials minimized delays. Ergonomic improvements also played a key role, supported by computer vision systems that identified inefficient or physically demanding movements and enabled workspace redesign.

These incremental changes delivered substantial results: assembly time for the DT2-550 was reduced by approximately 67%, worker travel distance dropped by around 37%, and 15 safety improvements were implemented—all within a single week.

However, lean is not a one-time initiative. Keresteci has planned 60 additional kaizen events for 2025, reinforcing a culture of continuous improvement.

“We are committing to increased production capacity, and each kaizen event brings us closer to that goal,” he said. “This was an important step forward and a clear indication that we are on the right path.”
